passes between the rollers 3 and 4 above the Patented Sept. 7, 1937` PATENT OFFICE WINDOW MOUNTING Edward F. Tannewitz, Detroit, Mich., assignor to The lletroit Gasket and Manufacturing Company, Detroit, Mich., a corporation of Michigan Application July '7, 1932, Serial No. 621,221

16 Claims.

My invention relates to window mounting such as shown in my Patent Number 1,670,321, of May 22,1928, and objects of my improvements are to reduce the cost of manufacturing the same and to produce a better article.

I accomplish this object in the way and by the means illustrated in the accompanying drawing, in which: V

Figure 1 is a diagrammatic side elevation of a series of rolls and illustrating the process of my invention.

Figure 2 is a section on the line II, II, Figure 1.

Figure 3 is a perspective View of a portion of the sheet formed by the apparatus of Figures 1 and 2, showing its front edge in section.

Figure 4 `is a View similar to Figure 3 showing a portion of one of the strips into which the sheet of Figure 3 is cut.

Figure 5 is a. view similar to Figure 4 showing the side edges of the strip turned over toI adapt the same to be combined with the base-strip to form the run and complete the channel strip.

Figure 6 isa perspective view of the channel strip embodying my invention the front end being shown in section.

2, 3, and 4 are forming rolls with axes in a vertical plane. The rollsv'2 and 3 have plain cylindrical surfaces andthe roll 4 has grooves 4a formed around its periphery. These grooves are located in pairs intermediate the ends o f the roll and the grooves of each pair are at a distance apart equal to the two edge portions of the severed strips that are turned over in forming the bead for the run, as hereinafterv described. The grooves at the ends are located one half this distance from the end of the roll.

The distance between the pairs of grooves and between the end pairs and the end grooves is equal to the `breadth ofthe channel-run-strip between its thickened edges, as hereinafter described.

5 isa sheet of cushion material formed from a mass of plastic material by passing the same between the rollers 2, 3, and 4, as illustrated in Figures 1 and 2. This material is made up of comminuted cork held together by a suitable binder.

6 is a sheet of felt. This sheet is fed between the rollers 3 and 4, as illustrated and the plastic material is fed between the rollers 2 and 4 and sheet 6, as illustrated in Figure 1, and is formed into a sheet by the action of the rolls 2 and 4. The upper surface of the cloth or felt 6 is provided with an adhesive` cement and as the rolls (Cl. 154m2) press the sheet 5 against said surface it is firmly united thereto.

The plastic material 5, as it passes between the rolls 2 and 4 iscompressed into the grooves 4a sothat ridges 5a are formed thereon of approximately semi-cylindrical shape in cross section.

After passing through the rolls, as above described, the plastic cushion material and felt is formed into a composite sheet illustrated in Figure 3, having the cork 5 with the ridges 5a. upon one side and the felt sheet 6 upon the other side. This composite sheet is now divided into strips by cutting the same longitudinally between the ridges 5a, of each pair, as illustrated at 56 in Figure 3. The strip thus formed is illustrated in Figure 4.

The edges are now turned over the ridges 5a, 5a, as illustrated in broken lines in Figure 4, forming the construction illustrated in Figure 5 having thickened edges constituting beads a, a. This strip is then placed in the cavity ofy the base-strip 8, as illustrated in Figure 6, and se- Cured therein by stitches 86 or otherwise, the beads a., a, coming adjacent tothe edges of the base-strip 8 and forming the window-channelrun which I have designated, as a whole, by the letters A, A. This brings the resilient and durable cushion cork material against the inner surface of the base-strip 8 and with the overlapping felt covering the beads a, a, so that when the glass is interposed between said beads it engages against the felt and the felt is resiliently held in shape by the cork.

Vlhat I claim is:

1. In a process of forming a strip to be used in making a windowchannelrun, passing a plastic material between rolls and forming a sheet having integral spaced parallel longitudinal ridges in connection with a sheet of felt so that the two shall be united together to form a composite sheet with the two materials upon opposite surfaces, and the ridges exposed on one of said surfaces, folding said composite sheet into substantially U-shape, and forming said ridges into bead portions at the entrance opening of the channel.

2. In a process of `forming a strip to be used in making a window-channel-run, passing a plastic material between rolls and forming a sheet therefrom with spaced parallel longitudinal ridges i along its sides in connection with a sheet of felt so that the two shall be united together to form a composite sheet with the two materials upon opposite surfaces, and the ridges exposed on one of said surfaces, folding said composite sheet| into substantially U-shape, and forming said ridges into bead portions at the entrance opening of the channel.

3. In a process of forming a strip to be used in making a window-channel-run, passing a plastic material between rolls to form a sheet therefrom with ridges along its sides in connection with a sheet of felt so that the two shall be united together to form a composite sheet with the two materials upon opposite surfaces, and turning the edges of said composite strip over said ridges.

4. In a process of forming strips to be used in making a window-channel-run, passing a plastic material between rolls to form a sheet having spaced integralparallel longitudinal ridges in con-- necticn with a sheet of felt so that the two shall be united together to forzn a composite sheet with the two materials upon opposite surfaces, said sheets being of the width of a plurality of strips required and then cut ing said sheet to form strips of the width required.

5. In a process of forming strips to be used in I making a window-channol-run, passing a plastic material between rolls to form a sheet therefrom with spaced parallel longitudinal ridges in connection with a sheet of felt so that the two shall be united together to form a composite sheet with the two materials upon opposite surfaces and the ridges exposed on one of said surfaces, said sheets eing of the Width oi a plurality of the stripsvrequired and then cutting said sheet to form strips of the width required, said ridges heing properly relatively arranged and extending from the plastic sheet, substantially as and for the purpose described.

G. In a process of forming a strip to be used in making a window-channel-run forming a sheet of plastic material with spaced pairs of ridges along its sides upon one surface of a sheet of felt and causing it to adhere thereto so that the two shall be united together to form a composite sheet with the two materials upon opposite surfaces, and turning the edges of said composite strip over said ridges.
